The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Vitality gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence in line with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace rates https://cruzcdczv.bloggadores.com/32369730/the-2-minute-rule-for-er-yb-yab-crystal
